Thanks, however that's not really my case. If you write a sentence in the RichTextLabel that spans several lines, apply the [fill] tag and try to push the word on the end of one line to the next one, either by pressing enter, or by pushing it with spacebar, you'll see an indent appear, because of the way that enter starts a new paragraph or that the [fill] tag treats spaces. The last line of the paragraph behaves as if it was aligned to the right, instead of filling the entire length of the RichTextLabel and the spacebar takes up space on the end of the line, which is why the text appears indented. What I was looking for was some kind of linebreaker that wouldn't start a new paragraph - the line that was broken would still fill the width of the RichTextLabel. But thanks for your help!
